Title: Improvements in or relating to apparatus for electrical control of the angular position of a rotary element in accordance with the phase sense and magnitude of an electric voltage
IPC: G05D3/14
Filed: 1955-10-31
Abstract: 819,639. Electric correspondence control systems. HASLER & AKTIENGESELLSCHAFT WERKE FUR TELEPHONIE UND PRAZISIONSMECHANIK. Oct. 31, 1955 [Nov. 5, 1954], No. 31046/55. Class 40 (1). The phase sense of the signal in the rotor 1 (Fig. 1) of a selsyn receiver is converted by a phase-sensitive circuit 2 into a direct current of polarity dependent on the phase-sense to energize one of two relays 3, 3<SP>1</SP>, thereby causing one of two oppositely rotating gear-wheels 5, 51 to engage with a disc 8 driving the rotor shaft 7 until the signal is eliminated. A brake drum 10 is simultaneously withdrawn from disc 8 by an electromagnet 11 energized by the D.C. flowing in relay 3 or 3<SP>1</SP>. The phase-sensitive circuit 2 (Fig. 2) comprises two thyratrons 12, 12<SP>1</SP> whose anodes 47, 47<SP>1</SP> are fed with A.C. in opposition, and whose grids 14, 14<SP>1</SP> are fed in parallel with the amplified error signal so that only one thyratron will fire for, a given phase of error voltage at 16, the pulsating D.C. flowing through energizing winding 17 or 17<SP>1</SP> of relay 3 or 31, the firing current of both thyratrons flowing through the brake winding 18. Additional bias is applied to the thyratron grids via rectifiers 19, 19<SP>1</SP> and capacitors 20, 20<SP>1</SP>. The amplified error voltage in windings 37, 371 may be further amplified by triode valves with A.C.-fed anodes before being taken to the grids 14, 14<SP>1</SP> of the thyratrons 12, 12<SP>1</SP>. If the angular transmitter and receiver are D.C. units, the D.C. error signal in the receiver rotor is fed at 31, 31<SP>1</SP> (Fig. 4) to the grids of valves 29, 291 whose anodes are A.C.-fed in parallel. The valve receiving the positive polarity of the error signal passes an anode current which upsets the equality of voltage between anode resistors 32, 321 and the resulting A.C. flow through capacitor 34 is amplified by transformer 35 and fed in parallel to A.C.-fed thyratrons 12, 121.

Title: Arrangement for converting electrical signals into optical signals
Inventor: PLAUSCHIN ULRICH
IPC: H04B10/50
Filed: 1971-07-02
Abstract: 1293890 Light modulators DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN 2 July 1971 31093/71 Heading H4F In a light modulator, a gas discharge lamp G is connected through a resistor R to a voltage source U 0  and via a diode D to a current source S. Ignition is controlled by a semi-conductor arrangement H, e.g. a plurality of series connected transistors with associated voltage dividers in turn controlled by duration or frequency modulated pulses. When a pulse is applied, the semi-conductor arrangement becomes conductive and the lamp is ignited by voltage source U o  so that a current flows through the lamp from the source S which remains unchanged from one pulse to another. In a modification, the semiconductor arrangement is connected across the lamp so that current flows only when the semiconductor arrangement is blocked. In these arrangements a high resistance voltage source is used. If a low resistance voltage source is used, electronic switching to connect it to the lamp only for the duration of the ignition is required.

Abstract: 1,146,656. Measuring tension electrically. ALLMANNA SVENSKA ELEKTRISKA A B. July 12, 1966 [July 13, 1965], No.31237/66. Heading G1N. The distribution of tension across a moving strip from a rolling mill is measured by leading the strip over a pressure sensitive roll comprising an inner stationary shaft 1, an outer casing 9, in contact with the strip, and rotatably mounted on the shaft by bearings 3, each associated with a pressure sensitive device 7 the output of which is indicative of the local pressure on the roll and therefore of the local tension in the strip. In the embodiment, the pressure sensitive devices 7 are located in a groove 6 in the shaft in contact with the inner surface of a bearing ring 5 attached to the shaft. A second bearing ring 4 is rotatably mounted on the ring 5 by ball bearings 3 and carries the casing 9. The ring 5 may be attached to the shaft by distance pieces or wedges (11), Fig. 4 (not shown), which also serve to generate a pre-stress in the associated device. Alternatively elastic membranes or springs (12), Fig. 5 (not shown), may be used. Finally two rings 15, 16, Fig. 6, may be used, inter-connected by radial spokes 17 round two of which coils 18 are wound whose inductances vary in dependance on the applied pressure. Alternatively the devices may be located between the outer bearing ring 4 and casing 9. The casing 9 of elastic material may consist of a single tube as long as the roll or a number of tubular parts (10), Figs. 2-3a (not shown), the joints being arranged at the centre of each bearing, Fig. 2 (not shown), at either end of a pair of bearings, Fig. 3 (not shown), or between each bearing, Fig. 3a (not shown). In the latter case the longitudinal surface of the casing is slightly rounded so that the strip does not contact the joints. If necessary a further thin layer of elastic material, e. g. PTFE, may be provided to cover the joints. Alternatively the bearings may be arranged closely adjacent each other so that the casing 9 may be omitted.

[Also in Group XI] An electric resistance especially for heating clothing or blankets is made by rendering conductive a material composed of insulating threads or fibres, applying thereto an insulatng coating to stiffen the material and stabilize its resistance characteristics, and then cutting the material to form the resistance which may be given a final insulating coating. A woven or knitted fabric e.g. cotton, silk, nylon, glass is rendered conductive as described in Specifications 572,071, [Group XXXVI], and 648,087, [Group XI], and is then coated by dipping, spraying or rolling with a hardenable insulating compound, e.g. a synthetic resin such as neoprene which may form a film in each interstice of the fabric, the fabric being then moderately stiff but flexible. Strips cut from this metallized material are then coated on both sides by sheet insulating material overlapping around the strip, or by a liquid coating, e.g. of neoprene which may fill the interstices of the fabric strip. The coating materials are compatible with one another and may be fused or hardened into a unitary mass, e.g. using partly cured plastics or a solution of neoprene in toluene for liquid coating, preferably with magnesium oxide as an acid acceptor or thiocarbanilide as an accelerator for heat vulcanization. The coated strips are sewn or stuck on garments or blankets. Specification 721,044 also is referred to.
